So i got my b16a swap into my 1994 Dx hatchback. Pulls good but i can't get the Cel Code #22 Vtec Pressure i believe? To go away. My buddy who also just swapped a gsr into is 93 hatch has the same problem.

Ive tried 2 diff. vtec solenoids, checked the wiring, Check to make sure the vtec wires were pinned right on the ECU(since mine was a 94, vtec wasn't ran on the chassis) I'm really at a loss as to what is going on?

If anyone could help it would be greatly appreciated! Also, before you tell me to go search ive been doing it for days on end now!

Thanks,

Brandon

i had that code too. i switch everything...so i gave a good snug bump to the stock oil pressure sending unit..and the light went off....but still no vtec..my timing is off to(dizzy)
you can overide the oil pressure swith you know?

Ok well that still doesnt help me because even if i override the code, Idk if theres actually vtec there. It pulls fine but from what ive heard b16a's have a loud vtec.

Mister JDM

for vtec oil pressure switch put one to a ground and one goes to the ecu.just wrap one wire to a bolt on the valve cover and other stays to the ecu.

B Dap

already did that to. Thanks tho!

Anybody else?

I had the same problem when i swapped in my b16 into my del sol. The problem is that your ecu is looking for the vtec oil pressure switch to send a signal to the ecu telling it the vtec is either engaged or not. Your motor (like mine) dose NOT have a vtec oil pressure switch. SO what your gonna have to do is wire up a bypass to "Trick" the ecu into thinking its getting the signal its looking for. Here is a great link to wire up the bypass: https://honda-tech.com/forums/honda-civic-del-sol-1992-2000-1/vtec-oil-pressure-switch-bypass-really-simple-1693528/. And Yes the b16 vtec is very loud, when it kicks in you''ll know it. Mine hits right at 5,600.

Awesome dude thanks! I will try it out and let everyone know if it works or not

B Dap

Well it didn't work for me...im gonna try it with the other vtec solenoid. JW15U where did you run that wire between the 2? A4 and D6 that is. Right before the connectors on the ECU or by the solenoid itself?

Im still not getting vtec i dont think. I got the check egnine light to go away but i deff. cannot hear the vtec crossover.
